I see GPU utilization and this show the load.
Below that I see a value for d3d usage. What is this?

what is d3d usage?
- Thread starter somebodycool
- Start date
This is the amount of memory used by the GPU via DirectX/Direct3D. It doesn't cover memory usage via other interfaces (like OpenCL for example).
Unfortunately, AMD doesn't seem to offer an universal way how to report exact memory usage of the GPU (like nVidia), so this is currently the only way how to get a picture of memory usage.

I see:
GPU Utilization
GPU D3D Usage
GPU D3D Memory Dedicated
GPU D3D Memory Dynamic
I thought GPU D3D Memory Dedicated showed the memory used by the GPU. Dynamic showed the memory for the graphics card (gpu and memory) that is in the system memory.
GPU D3D Usage is definitely not showing the amount of memory used by the GPU.

How is gpu utilization different from d3d usage?
If i play a d3d game, the utilization and d3d usage should be the same?

Theoretically they should be close.
"GPU Utilization" is read straight from the GPU internal registers, so this should be the more precise value and it should cover the entire GPU.
"D3D Usage" is read via Direct3D, so it covers only this interface.
Unfortunately, hardware vendors don't give out information that would help us to understand such things, so sometimes we're just left to try and see...

Hey Guys my name is Mark.Well i think that D3D is used to provide three perspective design in programs where performance is essential, such as activities. D3D also allows programs to run fullscreen instead of included in a screen.Thanks!!

AMD A10-6800K
I set CPU 4000 MHz / GPU 800 MHz (in idle they fall to 2000 / 300)
Windows 7 SP1 (default aero theme)
Catalist 13.152.1.8
HWiNFO x64 4.2.6.0
In idle I see 20-60% Utilization and 0-3% D3D Usage.
In max load I see 99% Utilization and 100% D3D Usage. No matter - D3D or OpenGL!
Furmark - OpenGL - 100% D3D Usage.
After runing OpenGL Extension Viewer 4.1.3 test:
Utilization (max): 94.0%
D3D Usage (max): 96.9%
Hello Martin, I can't find the interface to get GPU D3D Usage in Direct 3D, can you tell me the specific interface? Looking forward to your reply. Thank you very much!Not quite sure I understand what you’re asking but
D3D = Direct3D
Hello Martin, I want to ask which Direct3D function can get the GPU Usage information in the graph, possibly DXGIAdapter? DXGIFactory? .. I have been puzzled by this question for a long time. I hope to get your answer. Thank you and look forward to your reply
Thank you very much. I'll look it up
Hello Martin, I tried to find information on Performance Counters from d3d9/d3d11/d3d12/dxgi, but I still found nothing. I found ID3D11Counter/D3D11_QUERY_DATA_TIMESTAMP_DISJOINT, but these do not seem to obtain GPU Usage, can you give me a hint? Thank you and look forward to your reply。 ：）
